Security Center in Tenable Enclave Security System Requirements
Note: If you migrate from a Tenable Security Center on-premises deployment to a Tenable Enclave Security deployment, you must use an external PostgreSQL server. Before you migrate, the Tenable Security Center on-premises deployment must use the same external PostgreSQL server that you plan to use after the migration.
External PostgreSQL Requirements
You can install Tenable Security Center configured to work with a PostgreSQL instance managed by you. PostgreSQL is required for certain features. For more information about connecting a PostgreSQL database, see Connect an External PostgreSQL Server.
This is a required configuration if you have more than 100K hosts. It is also recommended that wal_segment_size is set to be at least 64MB.
If you set up your PostgreSQL instance in a cloud environment, the following are guidelines for choosing your instance size. Note that the disk space in the following table is only for PostgreSQL data, and does not include any other OS or other dependencies you have.
